Answer
The wave nature of electrons is demonstrated through electron diffraction. This phenomenon occurs when electrons are passed through a narrow aperture or around an obstacle, resulting in a diffraction pattern, which is characteristic of wave behavior.

Answer
The particulate nature of light is evidenced by the photoelectric effect. This effect occurs when light (photons) hits a material and causes the emission of electrons, demonstrating that light possesses both wave-like and particle-like properties. This confirms that individual photons can have sufficient energy to remove electrons from a material.
